To @ZZ whom it may concern..-

Be it known that I, THOR A. THORSEN, a subject ofthe King of Norway, residing` at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in l-Iand Planing-Machines, of which the following is a specification.

The more prominent ob jects of. my invention are to provide a simple, compact, and etticient construction of hand planing-machine which can be readily carried from place to place within a workshop and applied at will either to a vise or to any ordinary bench, but more particularly to the former, and when so applied worked by hand, whereby the entire machine may serve as a comparatively small tool or device having a greater range ot' utility and capable of various uses not incident to planing-machines as constructed prior to my invention.

Further objects are to adapt the machine to a great variety of work, and to provide certain novel and improved details, all serving to increase the general utility and efficiency of the machine.

In a hand planing-1nachine characterized by my invention the main frame or stationary body portion of the machine is adapted for application to a vise, andthe reciprocating carriage whereon a suitable toolsholder is supported is arranged so that the tool can be placed in position to act upon such work as may be placed within a vise, whereof the movable jaw preferably serves as one of the work-holding jaws, while the stationary jaw or stationary body of the vise, which is provided with the stationary jaw, serves as a holder to which the body of the hand planing-machine can be rigidly attached. A horizontal guideway for the carriage is supported upon the body portion of the machine, and the said carriage is provided with an adj ustable slide to which the tool-holder is attached. The carriage is conveniently operated by a hand-lever, and at each back-stroke on the part of the carriage the slide is adjusted to a proper extent by an automatically-operating feed device. In order to permit the tool to work within a more extended field and from different standpoints, the guide for the carriage is pivotally attached to the body portion of theniachine and extended out therefrom, whereby it may, when desired, be swung around so that the direction of reciprocation of the carriage can be changed to any desired extent. The body portion of the niachine is also provided with a laterally-arranged work-holding bracket which may upon certain occasions be employed for holding` certain kinds of work, and, it desired, the said body portion of the machine can'be removed from the vise and applied. to an ordinary work-bench.

Certain details ot' construction are herein particularly described in connection with the accompanying' drawings, in whicl1- Figure l represents in perspective a hand planing-machine embodying the principles ot' my invention and applied to a vise. Fig. 2 is a top plan view of the same with the jaws t of the work-holding bracket I omitted for convenience ot' illustration. Fig. 3 represen ts a vertical section taken transversely through Fig. 2 on the line 3 3, the vise handle and screw being, however, shown in. elevation. Fig. et represents in elevation the rear side ot the machine shown in Fig. l, the vise and bracket being, however, omitted. Fig. 5 represents, on a larger scale, a portion ot" Fig. et, but shows a section taken through the bracket h on the line 5 5, Fig. 2, said Fig. 5 being mainly designed to show 'the position. of the pawl-carryin-g arm e* at the moment that it is about to ride upwardly along the cam or ineline e5. Fig. 6 represents in perspective the reciprocatory carriage. Fig. 7 represents a section taken through said carriage on the line 7 7, Fig. G. Fig. S represents in plan the tOp of the body portion A ot' the machine. Fig'. 9 represents a section taken on a vertical plane through the guide-plate l5 and the top of t-he body portion A of thc machine. Fig. lO

represents in perspective the machine applied to a work-bench.

In said drawings, A represents the main frame or the body of the machine, and B denotes a block or plate, which is arranged upon the body A and adapted to serve as a guide for reciprocating slide of carriage C. The carriage C carries a suitably-constrncted toolholder, D, and serves to move the tool forward and back along the work. After each IOO n the rotation of the feed-screw.

'e @geen forward stroke on the part oix the carriage l primarilysupported from abedeplate,B,which the tool is, by an automatic feed device, shifted or fed to a proper extent in a direction transn versely to the movement of the carriage. To such end the tool-hohler is attached to a slide, E, which latter is in turn supported upon the carriage C and arranged so that it can be adjusted by a 'feed-screw, c, in a direction transverselyto the lineot' reciprocation of the carriage. As a simple construction the carriage C may consist of an oblong plate, Figs. l and 7, provided along its bottom side with a longitudinally-arral'iged dovclail channel, c, and provided across its top side with a dovetail channel, c', whereby the guide B may [it the bottom channel, c, so as to propcrl y vguide and steady the carriage, while on the other hand a rib, e', on the under side otl the slide E may tit the top channel, c, of the carriage, so as to steady a-nd direct said slide in its adjustment.

The feed-screw c is mounted in suitable bearings upon the carriage and engages the slide, whereby said slide can be adjusted by The feedscrew is at each return or back stroke oi' the carriage actuated by a pawl or like device, to which end the feed-screw `is herein provided with a ratchet, e?, which is at each baclcstroke of the carriage positively engaged at a proper moment by the pawl ef". either weighted or spri11g-controlled, and is arranged upon a vibratory arm, c", Fig. 5, which is carried with the carriage C, and which during the back-stroke of the carriage is caused to ride along a stationary cam or incline, e5. The cam or incline c5 causes an upward swing on the part of the pawl-carrying arm, so that the pawl may positively engage the ratchet, and hence operate the same. As a means for supporting said cam or incline, it can be adj ustably attached by a setscrew or screw and thumb-nut, e, Fig. 5, to a bracket, l), which latter is conveniently formed by a bent plate or bar having its ends secured to the under side of the guide-plate B, as indicated by dotted lines in Fig. 2. It will be observed that the guide-plate B fits within a groove, c, in the under side of the carriage C, and that the bottom side of such portion of theguide-plate B as extends beyond the body A of the machine is exposed, whereby the bracket b can be attached to the under side ot the plate B, as aforesaid. The bracketl) also provides a convenient support for the Afulcrum f of a hand lever, F, which is operated to reciprocate the carriage. This handL lever is connected with the carriage by means ot' a pitman or connecting-rod, j", which is at one end pivotally attached to the lever and at its opposite end pivotally connected with the carriage by a universal joint, f2, (see particularly Fig. 7,) whereby perfect Freedom ot' operation is attained.

By the foregoing' arrangement the reciprocatory carriage, the feed device, and the device for reciprocating the carriage are all The pawl c may be also constitutes a vguideway for supporting` and guiding the carriage. This guide-plate ll is adjustably secured upon the body A, so

that it may be adjusted with reference to the position or character ot' the work. To such end the guide-plate is pivoted upon the body A by a pivot, h', about which the lgu'ideplate can be swung when so desired. rlhe guideplate B can he locked in its adjustment in any suitable way-as, lor example, it can be provided willi screws (1)2, arranged to engage nuts which are confined within an annular ianged or l channel, c, formed in the top ot the body A, as illustrated in Figs. S and El, in which way the screws can be either adjusted to tighten the nuts aga-inst the upper walls of the lower horizontal portion of the channel or adjusted so as to loosen the nuts and permit them to slide along the ch an n el.

The main .trame or body A ol' the machine is ad aptcd to be placed and held with in a vise, to which end it is formed with an open bottom and otherwise suit-ably adapted to iit upon or receive one of the jaws of a vise, as best shown in Fig. 3, wherein the body A of the machine is shown placed over the stationary j aw y of a vise, G. The opening' a in the top ot said body serves to receive the upper portion ot the vise-jaw (j and permits the machine to be set sufficiently low down with reii erence to the work, which, for example, may be clamped between the movable jaw g of the vise and one of the outer vertical sides of the body A ot' the machine, as in Figs. l, 2, and 3, wherein a piece of work is shown clamped between the body A and one of the visejaws. In connection wit-h such arrangement a gage, 71, can bc ad justably attached to the body A of the machine.

The body A is provided with one or more screws, a9, whereby it can be held rigid with the stationary jaw or stationary body of the vise, so that the machine will retain its properY place when the movable jaw of the viseis adj usted for the purpose of putt-ing in or taking out work. The said body A is at what may be termed its front side provided with one or more, butpreferablyacouple, of set-screws, a3, which, for example, can be adjusted so as to vary the angle at which the body can be held relative to a plane parallel with the visejaws or the work adjusted in position, as may be desired.

The tool-hol der is, by preference, adj ristably attached to the slide E, and to such end the slide is provided with a dovetail rib, el en gaging in a dovetail groove in the back o'l' the tool-h old er, wh ich 'latter can be ad j usted along said rib by an adjusting-screw, E', arranged to extend along a space or recess, e9, in the vt'ace ot the rib ci and provided at either end (or both) with a suitable handle, ci. ln connection with said screw t" any suitable pawl and ratchet or other vlocking device can be TOC TIO

employed. The feed-screw is also desirably provided with a crank or hand wheel, el, so that att-er the slide has been automatically adjusted in one direction to the required eX- tent the crank or hand wheel. el" can be operated so as to retract the slide.

`In Figs. l and 2 the body A is at one otl its sides provided with a work-holding bracket, l, in order to enlarge the scope ot action ot the machine and l'urthermlapt it tovarious kinds olf work.

The bracket l eau be arranged upon the body as a permanent tixture; but l prefer to (letachably secure it to said body in any proper mechanical way, it being, for example, obvious that as one of a variety of modes for attachment the body A can be provided with holes a, as in Fig. l0, for such bolts or screws as may be employed for holding the Abracket in place. The jawsi 'i are adjustably secured upon the bracket, whereby they can be set with reference to the size ot the work that is to be held between them, it being observed that as a simple way of adjustably securing the jaws upon the bracket the latter can be provided with T-ehannels [2 for the reception oli nuts, which are understood to engage the screws i3. ln like manner the bracket I can be provided with T-channels il along one or more of its sides, so that when desired the jaws ri 0r a similar pair ot work-holding jaws can be attached to the side of the bracket.

.In Fig. l() the body A ot the machine is shown secured upon an ordinar Y bench-top, K, in place ot being applied to a vise, ln said figure the work is shown held between one of the jaws and a serrated jaw, 1"", which latter is backed by the body A, it being' observed that the serrated jaw is here employed to hold a eylindric piece of work.

It will, however, be obvious that both of the jaws t can be used when the bracket is applied asin Fig. lO, and also that either or both of said jaws can be serrated or otherwise adapted with reference to the character of the work that is to be held between them.

Where the machine to be rendered applicable to a bench as well as to a vise, the body A can be itlanged at its base or otherwise adapted to provide bearings for bolts or clamping devices, it being understood,how ever, that such arrangement does not intertere with the removal ol.' the machine from the bench and its applieatitm to a vise.
